Kirkland Lake Discoveries hits 25.85 g/t Au over 3.00 m at Mirado Fault Zone

Toronto, Ontario--(Newsfile Corp. - September 9, 2026) - Kirkland Lake Discoveries Corp. (TSXV: KLDC) (OTCQB: KLKLF) ("KLDC" or the "Company") is pleased to report on results for an additional drill hole from the North Zone of the Mirado deposit. KLM26-030 successfully intersected multiple broad intervals of gold mineralization and high-grade gold, including 25.85 g/t Au over 3.00 m within a 7.24 g/t Au over 11.10 m interval at the Mirado Fault. This hole is part of the ongoing summer 2026 drill program at the KL South Project, 18 km south of Kirkland Lake, with 21 additional holes pending.

Highlights

KLM26-030 hit a silica-flooded zone grading 7.24 g/t Au over 11.10 m from 353.00 m including 25.85 g/t Au over 3.00 m at the Mirado Fault beneath the historical deposit as well as multiple broad lower-grade intervals closer to surface

KLM26-030 is the northernmost drill hole to date and has extended the stacked, steeply dipping gold mineralization of the North Zone an additional 125 m

The Mirado Fault, previously identified in KLM26-006, which assayed 2.46 g/t Au over 14.70 m including 12.52 g/t Au over 1.80 m, was intercepted at 353 m downhole and continues to bear high-grade gold 180 m along strike

Hole KLM26-047, situated 100 m northwest of the discovery holes at Mirado West, has intersected intense silica-chlorite alteration associated with sulphide mineralization in a structure from 369 m to 378 m downhole

21 holes pending results Eight from Mirado North and South

Seven from Mirado West

Six regional targets

Stefan Sklepowicz, Chief Executive Officer , commented: "Hitting 25.85 g/t gold over 3 metres at depth is exactly the type of intercept we were looking for to confirm our structural model. These high-grade feeder zones are the lifeblood of the major multi-million-ounce gold deposits in the Kirkland Lake camp. Demonstrating this high-grade continuity at Mirado drastically
